Multiple sclerosis: Jack Osbourne and other celebrities with the disease

Jack Osbourne, son of rocker
Ozzy Osbourne and
"The Talk" host
Sharon Osbourne, recently announced he has multiple sclerosis. The reality star joins a long list of celebrities from music, politics, television and film that have been diagnosed with the degenerative nerve disorder.

"I was just angry and frustrated and kept thinking, 'Why now?' I've got a family and that's what's supposed to be the most important thing,"
Osbourne says.

Osbourne was diagnosed just two weeks after the birth of his first child, Pearl Clementine, with fiancée
Lisa Stelly.

Interestingly, Ozzy was also
once diagnosed with MS in 1992 -- he even announced his retirement and played a farewell tour. But six months later, the Osbournes learned that it was a misdiagnosis.
